雖然工業(yè)控制機(jī)和可編程控制器本身都具有很高的可靠性,但如果輸入給PLC的開(kāi)關(guān)量信號(hào)出現(xiàn)錯(cuò)誤,模擬量信號(hào)出現(xiàn)較大偏差,PLC輸出口控制的執(zhí)行機(jī)構(gòu)沒(méi)有按要求動(dòng)作,這些都可能使控制過(guò)程出錯(cuò),造成無(wú)法挽回的經(jīng)濟(jì)損失。
影響現(xiàn)場(chǎng)輸入給PLC信號(hào)出錯(cuò)的主要原因有:
1)造成傳輸信號(hào)線短路或斷路(由于機(jī)械拉扯,線路自身老化,特別是鼠害),當(dāng)傳輸信號(hào)線出故障時(shí),現(xiàn)場(chǎng)信號(hào)無(wú)法傳送給PLC,造成控制出錯(cuò);
2)機(jī)械觸點(diǎn)抖動(dòng),現(xiàn)場(chǎng)觸點(diǎn)雖然只閉合一次,PLC卻認(rèn)為閉合了多次,雖然硬件加了濾波電路,軟件增加微分指令,但由于PLC掃描周期太短,仍可能在計(jì)數(shù)、累加、移位等指令中出錯(cuò),出現(xiàn)錯(cuò)誤控制結(jié)果;
3)現(xiàn)場(chǎng)變送器,機(jī)械開(kāi)關(guān)自身出故障,如觸點(diǎn)接觸不良,變送器反映現(xiàn)場(chǎng)非電量偏差較大或不能正常工作等,這些故障同樣會(huì)使控制系統(tǒng)不能正常工作。
?
影響執(zhí)行機(jī)構(gòu)出錯(cuò)的主要原因有:
1)控制負(fù)載的接觸不能可靠動(dòng)作,PLC發(fā)出了動(dòng)作指令,但執(zhí)行機(jī)構(gòu)并沒(méi)按要求動(dòng)作;
2)控制變頻器起動(dòng),由于變頻器自身故障,變頻器所帶電機(jī)并沒(méi)按要求工作;
3)各種電動(dòng)閥、電磁閥該開(kāi)的沒(méi)能打開(kāi),該關(guān)的沒(méi)能關(guān)到位,由于執(zhí)行機(jī)構(gòu)沒(méi)能按PLC的控制要求動(dòng)作,使系統(tǒng)無(wú)法正常工作,降低了系統(tǒng)可靠性。要提高整個(gè)控制系統(tǒng)的可靠性,必須提高輸入信號(hào)的可靠性和執(zhí)行機(jī)構(gòu)動(dòng)作的準(zhǔn)確性,否則PLC應(yīng)能及時(shí)發(fā)現(xiàn)問(wèn)題,用聲光等報(bào)警辦法提示給操作人員,盡快排除故障,讓系統(tǒng)安全、可靠、正確地工作。
